Answer 1

Resposta:

Explicação passo a passo:

$\frac{8}{10}+\left(-\frac{1}{5}+\left(\left(\frac{1}{4}-\frac{2}{3}\right)+\frac{1}{2}\left(\frac{1}{3}\right)^0\right)\right)\\\frac{8}{10}-\frac{1}{5}+\frac{1}{4}-\frac{2}{3}+\frac{1}{2}\left(\frac{1}{3}\right)^0\\\\\frac{8}{10}-\frac{1}{5}+\frac{1}{4}-\frac{2}{3}+\frac{1}{2}\\\\\frac{4}{5}-\frac{1}{5}+\frac{1}{4}-\frac{2}{3}+\frac{1}{2}\\\\\frac{3}{5}+\frac{1}{4}-\frac{2}{3}+\frac{1}{2}\\\\\frac{36+15-40+30}{60}=\frac{41}{60}$
